First produced from the iconic 1974 vintage, Phelps Insignia is the first proprietary Bordeaux-style blend produced in California. Primarily Cabernet Sauvignon, each vintage is comprised of the best grapes from Joseph Phelps Vineyards, initially from both grower and estate fruit, and beginning with the 2004 vintage, from entirely estate-grown fruit sources. Grapes from six of the Joseph Phelps estate vineyards go into Insignia: Spring Valley Home Ranch Vineyard in St. Helena, Banca Dorada Vineyard on the Rutherford Bench, Las Rocas and Barboza Vineyards in the Stags Leap District, Yountville Vineyard in the Oak Knoll District and Suscol Vineyard in South Napa Valley.
